    Several times the system freezed while working, everytime by pushing the start button about 20 sec it shuts down. After start up again the ventilator (CPU) was going very fast, only three lights keyboard flashed, dvd light flashed, some movements in HDD, nothing else, black screen. About 6 months ago a few times before the same problem but after a few attempts the computer starts up normal. At this moment it stays the same with fast ventilator. Battery is 2.85 V but bios time stayed normal. So I don't think it is the battery.

Hi,
There could be problem with the motherboard. You can try resetting the same.
1.Press F2 to enter the system setup.
2. Use the down arrow key and go to the option that says maintaince
3. Press enter and key down to the option CMOS defaults
4. Hit enter and reset defaults
5. Press escape and save changes and exit
6. check if the system boots up.


Before you perform the steps given above, unplug all external peripherals from the system like printers and webcams speakers etc. Your information is safe and there would not harm done to the information stored on the hardrive .


Thanks
proton

DELL 8400 MAKES A LOUD FAN NOISE AND WONT BOOT


There are 2 basic fans in Dell tower one for the power supply and the other for the Processor. If your computer is not booting then the Processor fan is most likely to be the culprit. What could be happening is that the Processor fan is no longer turning fast enough to cool the processor, so normal the processor when it over heats there is either protection to switch off the computer automatically or the computer won't boot. The best thing is to change the fan and make sure it is working properly but checking on the cables that they won't entangle on top of the fan to impede it's movement. You can easily damage your processor if the fan is not working properly.

Computer Randomly Cuts off


processor overheating. When it gets too hot it automatically shuts your pc down and boots it back up. Even if the fan is running, it could not be supplying enough cool air anymore.

Black screen


Some USB devices seem to cause this problem. I've had it myself. USB devices when hooked up cause the computer to freeze as it hard for USB drivers to be loaded outside of windows. Try updating you windows thru windows update though even updated I still run into the problem sometimes. If updating dosen't work you need to keep the drive unhooked while booting then hook up in windows.

Problem with Dell Inspiron 1100 series laptop


Most certainly a non working fan would cause this behavior. Laptops are much more susceptible to overheating. Fan failures can be hastened by regularly blocking the fan by doing things like using it on a pillow or soft surface. The behavior is exactly what you think.
